Lemongrass–Black Pepper Dungeness Crab with Rice and Braised Tokyo Turnips

Sweet Dungeness crab gets tossed in a glossy lemongrass and cracked-black-pepper sauce, with plenty of cilantro and lime to keep it bright. White rice catches the sauce, while gently braised Tokyo turnips bring a tender, mellow counterpoint—a good winter crab supper.

Lemongrass–Black Pepper Dungeness Crab with Rice and Braised Tokyo Turnips

Lemongrass–Black Pepper Dungeness Crab

Cracking the shells before cooking lets the aromatic sauce reach the meat. Briefly blooming the pepper and lemongrass develops their fragrance without overwhelming the crab's sweetness.

Ingredients

  • 2 whole cooked Dungeness crabs, about 2–2½ lb each before cleaning
  • 3 stalks lemongrass
  • 6 cloves garlic, finely chopped
  • 1 tbsp finely minced fresh ginger
  • 1 tbsp coarsely cracked black pepper
  • 2 tbsp avocado oil
  • 2 tbsp gluten-free tamari
  • 1 tsp honey
  • ½ cup water, plus more as needed
  • 3 tbsp unsalted butter, cut into pieces
  • 1 tbsp fresh lime juice, plus more to taste
  • ¾ cup roughly chopped cilantro leaves and tender stems
  • 1 lime, cut into wedges

Instructions

  1. Remove the crabs' top shells, gills, mouthparts, and viscera. Separate the legs and claws, cut each body into quarters, and lightly crack the thick leg sections and claws with a mallet or crab cracker. Pick away loose shell fragments.
  2. Trim the lemongrass and remove its tough outer layers. Finely mince only the tender pale cores; you should have about ⅓ cup.
  3. Mix the tamari, honey, and water in a small bowl.
  4. Heat the avocado oil in a wide, heavy pot or deep sauté pan over medium heat. Add the lemongrass and cook for 2–3 minutes, stirring, until fragrant and softened but not browned. Add the garlic, ginger, and black pepper and stir for 45–60 seconds.
  5. Add the tamari mixture and bring to a simmer. Add the crab, turn to coat, and cover. Heat for 6–8 minutes, turning the pieces halfway through, until the meat is steaming hot throughout. If the pan cannot hold the crab comfortably, work in two batches, dividing the sauce between them.
  6. Uncover and let any excess liquid reduce briefly; the sauce should cling to the shells while leaving a little to spoon over rice. Add a splash of water if it becomes dry before the crab is hot.
  7. Lower the heat and fold in the butter until glossy. Turn off the heat, add the lime juice and most of the cilantro, and toss gently. Taste the sauce before adding more tamari or lime. Finish with the remaining cilantro and serve with lime wedges.

Notes

  • Use freshly cracked pepper rather than finely ground pepper for a fragrant sauce with distinct peppery bites.
  • Keep the crab refrigerated while preparing the other components. It is already cooked, so the final simmer is for heating and coating rather than prolonged cooking.

Steamed Jasmine Rice

Plain, fragrant white rice absorbs the peppery crab sauce without competing with the shellfish.

Ingredients

  • 1½ cups white jasmine rice
  • 1¾ cups water, or the amount specified for your rice
  • ¼ tsp fine sea salt

Instructions

  1. Rinse the rice in several changes of water until the water runs mostly clear, then drain thoroughly.
  2. Combine the rice, water, and salt in a saucepan with a tight-fitting lid. Bring to a boil, cover, and reduce the heat to low.
  3. Cook for 15 minutes without lifting the lid. Remove from the heat and let stand, covered, for 10 minutes. Fluff gently before serving.

Notes

  • For a rice cooker, follow its water markings and cooking cycle.

Braised Tokyo Turnips and Their Greens

A shallow braise softens the turnips while preserving their delicate sweetness. Their greens and a little rice vinegar keep the side fresh against the rich crab sauce.

Ingredients

  • 1½ lb Tokyo turnips, with tender greens if available
  • ½ cup water
  • 1 tbsp unsalted butter
  • ¼ tsp fine sea salt, plus more to taste
  • 2 tsp unseasoned rice vinegar

Instructions

  1. Separate the greens from the turnips. Scrub the turnips and trim the root tips; halve small ones and quarter larger ones into roughly 1-inch pieces. Wash the greens thoroughly and cut into broad ribbons, discarding tough stems.
  2. Place the turnips in a wide saucepan with the water, butter, and salt. Bring to a simmer, cover, and cook over medium-low heat for 7–10 minutes, until a knife enters with slight resistance.
  3. Uncover and simmer for 2–3 minutes to reduce the liquid to a light glaze. Add a splash of water if the pan dries out before the turnips are tender.
  4. Fold in the greens and cook for 1–2 minutes, just until wilted and bright green. Add the rice vinegar and adjust the salt. The finished turnips should be tender but still hold their shape.

Notes

  • If the turnips have no usable greens, serve the glazed roots on their own.

Overall Timing / Workflow

The rice rests while the vegetables and crab finish, so the shellfish can go straight from the pan to the table.

Instructions

  1. 0:00 — Clean and crack the cooked crabs, then refrigerate. Prepare the lemongrass, garlic, ginger, cilantro, and sauce mixture.
  2. 0:20 — Rinse and start the rice. Trim and wash the turnips and greens.
  3. 0:30 — Begin braising the turnips and set the table with shell bowls, crab crackers, picks, and plenty of napkins.
  4. 0:35 — Start the crab aromatics. Let the rice finish cooking and rest covered.
  5. 0:45 — Finish the turnips with their greens and vinegar. Keep warm while the crab heats through.
  6. 0:50 — Finish the crab with butter, lime, and cilantro. Fluff the rice and serve immediately.

Plating

Family-style service suits shell-on crab and keeps the sauce accessible for spooning over rice.

Instructions

  1. Pile the crab onto a warmed deep platter and scrape all the aromatic sauce over and around it. Scatter the reserved cilantro on top and tuck lime wedges alongside.
  2. Serve the rice in individual bowls and the turnips in a separate shallow serving bowl, including their light braising glaze.
  3. Provide a communal bowl for shells and a spoon for the crab sauce.

Leftover Path

Picking the remaining crab makes the next meal easy and avoids repeatedly heating meat in its shell.

Instructions

  1. Pick leftover crab meat from the shells promptly, checking carefully for fragments. Refrigerate the meat and sauce in a shallow covered container within 2 hours and use within 2 days.
  2. Cool rice quickly in a shallow container and refrigerate within 1 hour. Refrigerate the turnips separately.
  3. For another meal, heat the turnips and rice with a splash of water, then gently warm the crab and sauce separately until they reach 165°F. Spoon the crab over the rice and finish with fresh lime and cilantro.
  4. Reheat only the portion you plan to eat.
